MacBook was not charging or providing power to new battery , but old battery was getting power and had to run laptop through that. Decided new battery was faulty. iFixit sent replacement. Did some more trouble shooting and found that likely culprit was MagSafe.
Repair was easy. Couldn't find my spudger from when I replaced my fan so used a large zip tie. Able to send replacement batter that was never opened back to iFixit.
Once again, I should have printed the instructions out in color. Very hard to see which screw needed to come out because the circles blended with the rest of the picture in grayscale.
